Which is better Anchor Hocking or Pyrex?

Are old Pyrex bowls worth anything?
Some vintage Pyrex can earn up to $3,000, reports NPR—nevermind that it’s not dishwasher safe, and it’s a pain to lug around compared to modern iterations. Sure enough, we found a 1950s set selling for $1,850 on Etsy, and one from 1960 for $700 on eBay. There’s even a rare vintage Pyrex bowl mold going for $1,000.
When did Corning stop making Pyrex?
Although the colorful opalware was (sadly) discontinued in the late 1980s, the factory in Charleroi is still making Pyrex pieces. World Kitchen took over the Pyrex brand in 1998, when Corning once again returned its focus to scientific glassware.
Why did my Pyrex dish explode?
When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. If the stress is too extreme, the bowl’s structure will fail, causing a spectacular shattering effect.
Is Pyrex unbreakable?
